deej is an open-source hardware volume mixer for Windows and Linux PCs. It lets you use real-life sliders (like a DJ!) to seamlessly control the volumes of different apps (such as your music player, the game you're playing and your voice chat session) without having to stop what you're doing. Control your microphone's input level. Lightweight desktop client, consuming around 10MB of memory. Runs from your system tray. Helpful notifications to let you know if something isn't working. The sliders are connected to 5 (or as many as you like) analog pins on an Arduino Nano/Uno board. They're powered from the board's 5V output (see schematic). The board connects via a USB cable to the PC. The code running on the Arduino board is a C program constantly writing current slider values over its serial interface. The PC runs a lightweight Go client in the background. This client reads the serial stream and adjusts app volumes according to the given configuration file.
